CUSTOM LENGTHS AVAILABLE! LaserPro Gold is one of the finest Spectra lines available. A unique pressure lock stabilizing process makes these lines thinner, slicker, stronger, and allows less creep in the lines. Very little break in time. Hand measured, sleeved, and tied by us to ensure accuracy to within 1/4 inch. We utilize an extra long sleeving loop, allowing for slight length adjustments to be easily done in a few seconds.
